Overview
Ordering number : ENN7107 Monolithic Digital IC LB11824M Direct PWM Drive Brushless Motor Predriver for On-Demand Water Heater and Air Conditioner Motors Overview The LB11824M is a direct PWM drive predriver IC for use with three-phase power brushless motors.
The LB11824M can implement a motor drive circuit with the desired output capacity (voltage and current) by using appropriate external transistors.
This device is optimal for motor drive in larger home appliances such as air conditioners and on-demand hot water heaters.
